PATENJI OOOO QEFICE- IMPROVEMENT IN FASTENINGS FOR SPINNING-RINGS.

Specification forming part of Letters Patent No. 117,934, dated August 8, 1871.

To all whom t may concern:

Beit known that I, J noon H. SAWYER, of Lowell, ofthe county of Middlesex and State of Massachusetts, have made a new and useful invention for Supporting' the Ring of a Spinnin g-Fraine or holding it down upon its rail; and I do hereby declare the saine to be fully described in the following speciication and represented in the accompanying drawing, of which- Figure 1 is a top view, Fig. 2 a side elevation, and Figs. 3 a-nd 4 are vertical sections of a ring and its rail with my improved retainer or device for holding or aiding in holding the ring to the rail. Fig. 5 is an under-side view, and Fig. 6 a transverse section of the ring-retainer as it appears when separate from the ring a-nd its supporting-rail.

The said retainer is specially applicable to the duplex race-ring-that is, one having the form as represented in the drawing, or made with two circular races, a Z), united by a short tubular neck or connection, c, such composing the ring A. The retainer B, as shown, consists of a at annulus provided with two projections or ears, d d, having holes e e through them to receive the fastening-screws ff, which go down through such holes and screwinto the rail C. The said annulus is split at and through 011e ofthe said' screwholes and ears, as shown, in order that it may be drawn open and sprung over the lower race of the ring and into the space between the two races, so as to encompass the neck ofthe ring and lap 011 the lower race.

Although the retainer is to encompass the lower race, the part to lap on the race may eX- tend entirely about the race, or may be in separate iianges to embrace the race on its opposite sides.

The great advantage of the said retainer is that, being socketed, as shown at g in Figs. 5 and 6, or lianged to receive and lap on the lower race vof the ring in manner as represented, it affords a very strong and durable support for the duplex race-ring and a means of readily adjusting it or centralizing it with respect to the spiudle.

I claim- The retainer, iianged or constructed with the ring-race socket, as described, and split so as to be sprung upon or over the lower race of the ring, all being substantially as explained.

JACOB H. SAVYER.
